ITEM  8.01 - OTHER EVENTS.

DUSA Pharmaceuticals, Inc. (the "Company") issued a press release on February
24, 2006, attached to and made a part of this report as Exhibit 99, reporting
statistically significant interim results from its 80 patient, multi-center
Phase II clinical study of photodynamic therapy (PDT) in the treatment of mild
to moderate photo-damage (sun induced skin aging) of the face.

Except for historical information, this report contains certain forward-looking
statements that involve known and unknown risk and uncertainties, which may
cause actual results to differ materially from any future results, performance
or achievements expressed or implied by the statements made. These
forward-looking statements relate to the possibility that additional parameters
will reach statistical significance, belief concerning the usefulness of the
product, and intention to consult with third parties regarding future
development towards regulatory approval. Furthermore, the factors that may cause
differing results include the uncertainties of completion of this trial and
conducting new clinical trials, the regulatory approval process, the marketplace
acceptance of the Company's products, sufficient funding to conduct new trials,
product development risks, maintenance of the Company's patent portfolio,
reliance on third party manufacturers, and other risks identified in DUSA's SEC
filings from time to time.
